By Sergio Toribio and Patrick Robbins TB4

What is the contraceptive?

  • Thin, beige, 1 3/4-inch square patch that sticks to the skin
  • releases hormones through the skin into bloodstream
  • prevents pregnancy

How does it work?

  • Combination of hormones (progesterone and estrogen) are released through the patch prevents ovulation
  • Hormones thicken mucus produced by cervix, which makes it harder for sperm to reach any eggs
  • Should be applied in one of four places: abdomen, buttocks, upper arm, or upper torso

How well does the contraceptive work?

  • 8 out of 100 couples will have a unintended pregnancy during first year of use
  • Depends if you use the patch correctly
  • For woman that way more than 198 lbs, the patch may be less effective
